I am referring to the emails confirming the subscription or the approval notification to the list administrator. These emails are generated during the respective actions, but when I look at the log on my mail server, some of the emails only have a sender but no recipient.
I don't know any circumstance where Mailman would send a message with no recipients.
What are the actual log messages in the Postfix log? Also, what's in Mailman's smtp.log?
Shouldn't the Postfix service on the Mailman server simply forward the email to the “external” mail server for sending? That's up to your Postfix configuration.
